APPARATUS FOR HEATING WATER.

SPECIFICATION forming part of Letters Patent No. 501,846, dated July 18,1893.

Application filed May 21 1892. Serial No. 433,855. (No model.)

To all whom it may concern.-

Be it known thatl, WILLIAM S. REED, a citizen of the United States,residing at Marshalltown, in the county of Marshall and State of Iowa,have invented certain new and useful Improvements in Apparatus forHeating Water; and I do declare the following to be a full, clear, andeXact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form a part of this specification.

My invention relates to improvements in apparatus for heating water andconsists of a boiler supported in a casing and having inlet and outletpipes which are inclosed in said casing, the latter forming a flue forheated air, which is enabled to heat the water in the pipes both beforeentering and while leaving the boiler.

It further consists of the combination and arrangement of partshereinafter fully described and claimed.

In the drawingsz-Figure l represents a perspective view of a heaterembodying my invention. Fig. 2 represents a central vertical section ofthe heater shown in Fig. 1.

Similar letters indicate corresponding parts in both the figures.

Referring to the drawings, A designates a boiler or tank formed of steelor other suitable material able to resist a high pressure of steam, andB and B designate, respectively, inlet and outlet pipes, which extendupwardly alongside of the said boiler A to the upper portion thereof,the inlet pipe B entering the boiler and passing downward therein to thelower portion thereof. Surrounding the boiler and the said water pipesis a casing or jacket C composed of sheet or cast metal, forminga iiue,through which hot air, for heating the contents of the pipes and boiler,is passed.

Leadingfrom the lower portion of the boiler through the casing C is adischarge pipe D, having at its outer'end a blow-olf valve or cock E forthe purpose of blowing off mud or other sediment from the boiler. Thecasing is provided with a bottom F, through which the pipes B,B arepassed, and to which they may be secured in any suitable manner, if

I desired, so as to be firmly and reliably held in place within thecasing. The boileris supported on braces or supports-D which rest on thebottom F of the casing. In the said 'bottom F is a central opening Ginwhich may be inserted the end of a pipe leading from some suitablesource of heat supply as astove, furnace or gasoline burner.

Connected or fastened to the lower part of the casing are feet II andthe upper part of the casing has a top or ornamental urn J thereon,whereby a iinished appearance is given to the apparatus. The upper partof the casing is also provided with an outlet for the escape of theheated air from the iiue. The lower ends of the pipes B and B areadapted to be connected with pipes leading respectively from a Watersupply and to the place of service.

H designates a gas burner located in the chamber within the casing belowthe boiler and having the support J which rests on the bottom of thecasing. The said burner is supplied by the pipe L and is provided withthe lighter K.

M is a small door in the lower part of the casing.

` It will be seen that by having the inlet and outlet pipes insideof thecasing and extending the length'of the boiler, the water is heated, bothbefore it enters and after it leaves the boiler, by the heat in theflue, thus raising its temperature without employing extra heat, therebyeconomizin g the heat in the iiue.

The heating apparatus herein described may be readily placed in anyapartment where desired, being removable and easily connected withsupply and discharge pipes. The cost of the apparatus is light, andowing to the simplicity of the parts it is durable and, if needingrepairs, easily put in proper condition.

Having thus described my invention, what I desire to claim and secure byLetters Patent is 1. A water-heater, consisting of aboiler, inlet andoutlet water pipes, and a casing surrounding said pipes and boiler,forming a flue, substantially as described.

2. A water-heater consisting of a boiler, inlet and outlet water pipes,the inlet pipe leading into the upper end of said boiler and ex- IOOtending downward to nearv the bottom there of, and a easing surroundingsaid pipes and boilers forming a ue, and having a bottom With an openingtherein, substantially as described.

3. Awater-heater, consistin g of aboiler, Water inlet and outlet pipes,a casing forming a Hue surrounding said boiler and pipes, the latterextending alongside said boiler, and a blow-oft cock for said boiler,the bottom of said casing having an opening therein, said parts beingcombined substantially as described.

4. A Water-heater, consisting of a boiler, Water inlet and outlet pipes,a casing with abot- .tom through which said pipes pass, and having anopening therein and a blow-olf pipe leading from said boiler throughsaid casing, surrounding said pipes and boilers forming a liue, and saidcasing having an opening atits upper end, said parts being combinedsubstantially as described.

.of said casing having an opening therein, said parts being combinedsubstantially as described.

6. A Water-heater consisting of a boiler, inlet and outlet pipes, acasing surrounding said pipes and boiler, a bottom for said oasing,supports for said boiler resting on said bottom, and a gasburner in saidcasing below said boiler, said parts being combined substantially asdescribed.

In testimony WhereofI affix my signature in presence of two Witnesses.

WILLIAM S. REED.
